The team addressed the problem of COVID-19 and its impacts on health and the environment. They developed a mobile app to alert users about social distancing and air pollution levels. The app utilizes data from NASA and other space agencies showing reductions in nitrogen dioxide and other pollutants from reduced industrial activity due to the pandemic lockdowns. The team's solution aimed to help prevent the spread of COVID-19 while improving air quality and environmental conditions.

1. TEAM: GORKHALI
Quite Earth

3. The Challenge
• Quite Planet
Quiet PlanetThe COVID-19 outbreak and the resulting
social distancing recommendations and related
restrictions have led to numerous short-term changes
in economic and social activity around the world, all
of which may have impacts on our environment. Your
challenge is to use space-based data to document the
local to global environmental changes caused by
COVID-19 and the associated societal responses.

4. Problem
• For the COVID-19 Space Apps Challenge 2020, taking the Quiet Planet as the
challenge, the team
• addressed the problem due to COVID19 (Corona) directly affecting the health.
Corona is a communicable
• disease caused by a new strain of corona virus which affects the whole health
(i.e. physical, mental, and
• social) of a person. There is no vaccine currently available for COVID-19 and
scientists are researching
• for its cure. The condition of the world is very critical; every activity has been
halted and people are
• bound to stay at homes as countries have issued lockdowns. Till the date, May
30, 2020, 300 thousandhave lost their lives and more than 5 million have been
affected by the virus. As the world already
• indicated the negative impact of air pollution and global warming on human
health, the following are

5. Problem
• some of the impacts:
• • Exposure to fine particulate matter of less than 2.5 µm in width (PM2.5) is
linked to heart attacks and
• irregular heartbeats, asthma, decreased lung function, and increased
irritability of airways which can lead
• to coughing and difficulty breathing (EPA). [Video on PM2.5 and its health
effects]
• • Exposure to surface-level ozone (O3) has similar impacts on public health as
PM2.5, causing
• shortness of breath, coughing, airway inflammation, aggravation of existing
lung diseases, such as asthma
• and chronic bronchitis, and chronic obstructive pulmonary disease (EPA).
• • Exposure to nitrogen dioxide (NO2) also can irritate respiratory pathways,
aggravating, for instance,
• asthma symptoms (EPA).

7. GPS
Here in the picture GPS of the world is shown. The picture
clearly addresses the situation of COVID-19 in different
parts of the world. Not only that, but the app developed
by
the team in order to maintain social distance also uses the
GPS technique.
While searching for data, the internet was a basic source.
Internet data was secondary data and Real-Time System
[RTS] through the app was primary data.

13. Solution
• As the team addressed the problem of COVID-19, an app that alerts people for social
distancing and
• harmful gasses was being developed. Firstly, we should know how COVID-19 transmits from
one person
• to another. Its major route of transmission is air. The air must be clean and pollution-free
in order to
• reduce the possible risks in the future. The excessive emissions of gasses like NH3, carbon
dioxide
• (CO2), and many other greenhouse gases as well as fine particulate matter decrease the
air quality. NASA
• also finds some of the data related to the quality of air which is listed below:
• NASA’s Air Quality group will be regularly producing images from data collected from the
• Ozone Monitoring Instrument aboard. The Aura satellite shows how the concentration of
nitrogen
• dioxide (NO2) is reducing due to only a few air pollutants as every industrial activity has
come to
• a halt. These changes are mostly driven by human behavior as a response to evolving
restrictions
• during the COVID-19 pandemic. The group also produces images of other air pollutants,
such as

14. Solution
• Sulphur Dioxide (SO2).
• All imagery will be archived on the Air Quality news page, as well as on
NASA’s Scientific
• Visualization Studio website. These images are free and publicly available.
• NO2 is primarily emitted from the burning of fossil fuels (diesel, gasoline,
coal) in automobiles
• and power plants. Therefore, changes in NO2 levels can be related to changes
in human activity if
• the data are properly processed and interpreted.
• Major anthropogenic activities that emit SO2 include electricity generation,
oil and gas
• extraction, and metal smelting. SO2 is emitted during electricity generation if
the coal burned has
• sulfur impurities that are not removed (or not “scrubbed”) from the plant’s
exhaust stacks.

15. App
• GuidelineWe can use this app as your pocket guide in
this pandemic.It will help you know the
recoveries,deaths and current covid 19 patients all
over the world as well as help you in travellingvl with
the help of nasa observatory map over pandemic.This
app also provides you volunteer feature.our volunteer
will help you for any query related to covid-19 as well
provides you guidance on each step.In this app you
can also get the comparision if ecosystem before and
after pendemic.Stay home,stay alert use....Fight

17. Our plan
• The Quiet Planet is
• all about preventive
• measures for
• COVID-19 by
• taking social
• distancing,
• reduction of
• pollution, and
• many more into
• consideration. We
• visualized different
• kinds of data
• through the
• internet. The team Gorkhali with 6 members; 4 from Nepal and 2 from India has developed a mobile app.
• We utilized the resources like NASA, ESA, JAXA, CSA, and CNES for the retrieval of necessary data.

18. Impact of our plan
• How to fight with corona with maintaining all
precaution .
• Exploring Uneven Gains in Urban Air Quality
• Impact of Air Pollution Reduction on the
Atmosphere
• Air Pollution Links to Water Quality
• Shedding (Night) Light on Pandemic Economic
